I asked Bruce months ago to give me his opinion but I did not get no reply whatsoever because i do not have the equipment and the knowledge to test it I decided to sell it on eBay he says that Corona has sent him a couple of these to test whether or not that's true I do not know he seems to be pushing Frsky instead I Aske Corona to send me one to test why don't you try.
